摘要： A device for reducing friction while maintaining characteristics identical to the pressure characteristics of a common oil pump based on provision of a plurality of discharge sources and a newly devised method of switching oil passages. The device is configured from a first discharge passage from a first rotor assembly to an engine, a first return passage that returns to an intake side of the first rotor assembly, a second discharge passage from a second rotor assembly to the engine, a second return passage that returns to an intake side of the second rotor assembly, and a pressure control valve whose valve main body is provided between a discharge port from the second rotor assembly and the first discharge passage. The first discharge passage and the second discharge passage are coupled, and a flow passage control is executed in each of: a low revolution range in a state in which only the first discharge passage and the second discharge passage are open; an intermediate revolution range in a state in which the first discharge passage and second discharge passage are open and the first return passage is closed while the second return passage is open; and a high revolution range in a state in which the second discharge passage is closed while the first discharge passage is open and the first return passage and second return passage are open.

摘要： The present invention enables the manufacture of a trochoid pump having a crescent which has been considered theoretically impossible by employing an inner rotor of a trochoid pump. An inner rotor having a predetermined number N of teeth that is equal to or larger than 4 is formed in advance. In order to manufacture an outer rotor with a predetermined number (N plus a natural number equal to or larger than 2) of teeth, row circles that are identical to a drawn circle are disposed so as to bring the row circles into contact with the tooth bottomland of the inner rotor tooth profile, the inner rotor tooth profile is rotated by half a tooth about the center of the inner rotor and the outer rotor tooth profile is also rotated by half a tooth of the predetermined number (N plus a natural number equal to or larger than 2) of teeth about a virtual center of the outer rotor including the row circles, an established center is determined from the virtual center or the like at the time at which the contact state is assumed, a reference circle is drawn that has a radius from the established center to the row circles and that has the total predetermined number (N plus a natural number equal to or larger than 2) of the equidistantly spaced row circles to form the row circles as outer rotor tooth tips, thereby manufacturing the outer rotor tooth profile.

摘要： An estimation system for estimating an injection-molding related cost comprises an input unit, storage, a data processing unit, and an output unit. The storage stores a mold estimation function for each of cost items of a mold used to produce a molded product, and a mold estimation reference value table for recording mold estimation reference values in association with prescribed conditions. The data processing unit acquires a fabrication condition of the molded product through the input unit, reads the mold estimation function and one of the mold estimation reference values from the storage corresponding to the fabrication condition, and estimates a cost of the mold based on the mold estimation function and the selected mold estimation reference value. The output unit outputs a mold cost estimation result made by the data processing unit.
